title = "Fast filterbanks for the low power MPEG high efficiency advanced audio coding decoder",
abstract = "The paper derives fast decomposition for the Quadrature Mirror Filter (QMF) banks of the Low power Spectral Band Replication (SBR) tools in the MPEG High Efficiency Advanced Audio Coding (HE AAC) decoder. The original computation-intensive matrixing operations in the filterbanks are decomposed into fundamental Discrete Cosine Transform (DCT) types and simple permutations. Hence, the computational complexity can be effectively reduced by using fast algorithms for DCT.",
